<p>Bug <a href="http://webkit.org/b/109230">109230</a>: REGRESSION(r130089): Scrollbar thumb no longer re-rendered on hover</p>
<p>For this test to pass, the below box should be green (in DumpRenderTree).<br>
Interactively, the whole box should turn green on mouseover, even if not over the scrollbar thumb.</p>
<div id="scrollable">
    <div id="content"></div>
</div>
</body>
